AfterWindow Company in San Anselmo, CA
Juniper Windows & Doors handles window replacement, window installation, and door replacement across San Anselmo, CA. Most homes here were built between the 1930s and 1970s, which means original single-pane windows, settled frames, and doors that no longer seal against Marin County’s damp winters and hot summer afternoons. We give every San Anselmo homeowner a written price before work starts, and we back each installation with the 365-Day Done Right Promise. Call us at (682) 281-2168 to schedule a free estimate.
Why San Anselmo Homes Are Different
San Anselmo sits in the Ross Valley, where summer temperatures climb into the 90s while winter nights dip into the 30s with heavy fog and rain. That swing tests windows and doors harder than coastal towns a few miles west. We see it in the field: wooden sashes that swell and stick during wet months, aluminum frames that sweat and stain interior sills, and exterior doors that warp enough to let daylight show through the weatherstripping.
The housing stock leans toward mid-century ranches, Craftsman bungalows, and a growing number of hillside homes along neighborhoods like Sleepy Hollow and the Seminary area. Hillside lots mean crews often work on slopes, shimming and flashing windows to handle runoff that flows downhill toward Sir Francis Drake Boulevard and the creek corridors. Some San Anselmo properties fall under local design review when visible from the street, so we factor that into material selection and lead times from the first visit.
Our Main San Anselmo Services
Window replacement and door replacement are the two jobs San Anselmo homeowners call about most. Here’s what each one involves locally.
Window Replacement in San Anselmo
Older San Anselmo homes often have single-pane wood windows that leak heat in winter and let afternoon sun cook interiors in summer. Replacement usually means measuring settled openings carefully, addressing any dry rot in the surrounding framing, and installing a modern unit with a much lower U-factor. In Sleepy Hollow and other hillside pockets, we pay extra attention to wind exposure and drainage. See the full breakdown on our Window Replacement in San Anselmo page.
Window Installation in San Anselmo
New construction, additions, and ADUs around San Anselmo need windows installed from scratch, not swapped into existing openings. That means integrating with new framing, flashing to current California code, and coordinating with your builder so the schedule doesn’t stall. We work with eight product lines, so a specific style or performance rating rarely forces a compromise. The step-by-step process is on our Window Installation in San Anselmo page.
Door Replacement in San Anselmo
Entry doors in San Anselmo take a beating from winter rain and summer sun. Warped slabs, worn thresholds, and outdated hardware are common. Replacement often involves reframing the rough opening and sealing the sill pan properly, especially on older homes near the creek where moisture finds its way in. We cover material options, security considerations, and local lead times on our Door Replacement in San Anselmo page.
